Slightly OT ....  FWIW ....

One quick-and-dirty way to check threads for any process is to use the 
ncurses-based 'htop' utility.  I much prefer this to 'top' for several 
reasons, including its ability to hide/display kernel threads, 
hide/display user threads (in a different color if you like), display 
with vertical and horizontal scrolling, assign processor affinity on the 
fly, ptrace/strace processes, and a lot more.

It's in Dag Wieers' rpmforge repository for CentOS.

The suggestions offered in this discussion are all very useful with 
regard to tuning Apache.
